staging/vboxvideo: prepare for drmP.h removal from drm_modeset_helper.h

2019-02-07T20:47:29+00:00

The use of drmP.h is discouraged and removal of it from
drm_modeset_helper.h caused vboxvideo to fail to build.

This patch introduce the necessary fixes to prepare for the
drmP.h removal from drm_modeset_helper.h.

In the files touched sort the include files

Build tested on x86 and arm allmodconfig / allyesconfig.

staging/vboxvideo: Add TODO

2019-02-06T15:59:12+00:00

Noticed while wondering what vboxvideo is using the ->master_set/drop
hooks for.

v2: Polish grammar a bit (Sam).

staging/vboxvideo: don't set dev_priv_size = 0

2019-02-06T15:59:12+00:00

The compiler already clears this for us.

More important, someone might look what this is actually used for,
and freak out about the dragon staring back at them.

drm/irq: Ditch DRIVER_IRQ_SHARED

2019-01-29T14:45:21+00:00

This is only used by drm_irq_install(), which is an optional helper.
For legacy pci devices this is required (due to interrupt sharing without
msi/msi-x), and just making this the default exactly matches the behaviour
of all existing drivers using the drm_irq_install() helpers. In case that
ever becomes wrong drivers can roll their own irq handling, as many
drivers already do (for other reasons like needing a threaded interrupt
handler, or having an entire pile of different interrupt sources).

v2: Rebase

v3: Improve commit message (Emil)

drm/irq: Don't check for DRIVER_HAVE_IRQ in drm_irq_(un)install

2019-01-29T14:45:06+00:00

If a non-legacy driver calls these it's valid to assume there is
interrupt support. The flag is really only needed for legacy drivers,
which control IRQ enabling/disabling through the DRM_IOCTL_CONTROL
legacy IOCTL.

Also remove all the flag usage from non-legacy drivers.

v2: Review from Emil:
- improve commit message
- I forgot hibmc, fix that

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.

To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.

v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.

v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.

This will also conflict with ongoing drmP.h cleanup by others I
expect.

v3: Rebase on top of atomic bochs.

v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
  other places (all suggested from Laurent adopted unchanged).
- sort alphabetically

v5: Actually try to sort them, and while at it, sort all the ones I
touch.

v6: Rebase onto i915 changes.

v7: Rebase once more.

staging/vboxvideo: Don't set FBINFO_MISC_ALWAYS_SETPAR

2019-01-15T15:14:47+00:00

It's a debug hack flag useful to work around driver bugs. That's not a
good idea for a new driver. Especially for a new drm driver.

Aside: the fbdev support should probably be converted over to the new
generic fbdev support.

Pull staging/IIO driver updates from Greg KH:
 "Here is the big staging and iio driver pull request for 4.21-rc1.

  Lots and lots of tiny patches here, nothing major at all. Which is
  good, tiny cleanups is nice to see. No new huge driver removal or
  addition, this release cycle, although there are lots of good IIO
  driver changes, addtions, and movement from staging into the "real"
  part of the kernel, which is always great.

  Full details are in the shortlog, and all of these have been in
  linux-next for a while with no reported issues"

drm: Improve dumb callback docs

Noticed while reviewing a patch from Eric. Also add a todo for the
dumb_map_offset callbacks (it should be simple to do, but piles of
work). Plus fix up vbox, because vbox.
